Hmmmmmm, all this "dogs are carnivores" stuff I don't buy, sorry, nothing you can do to convince me of that one. I am more in the camp of omnivore and
OPPORTUNISTIC carnivore
I've owned way to many dogs who literally BEG for fruits and veggies to believe other wise, Orson will raid the trash for lettuce and various veggies anytime he can......seriously PASS UP MEAT to get to them
I believe they don't need grains (as a whole, not each individual obviously) but hey, lots of people are lactose intolerant and we are BORN to drink milk eh? LOL
You are sort of correct here. Dogs are not obligate carnivores like cats. They can, and most of the time do
survive on a grain or plant based diet, but a large majority do not
thrive and live to their fullest extent on these diets.
If cats were fed exclusively plant material and no meat, they would die within a few weeks. That is why cats (big and small) are the only obligate carnivorous mammals on Earth.
The way I see it, and yes...*this is my opinion on the matter*...is that dogs like fruits and veggies and grains, not because they are a necessary component to their diet but they like the taste. Its like "cake and ice cream" to them. Our dogs don't get any fruits or stuff like that on a regular basis, but when they do the scarf them down like no one's business. Some people would think that if dogs ate them with such gusto that means they are necessary in their diet. I don't, because my dogs are all at their healthiest points in life on a PMR diet, without any fruits and veggies at all.
This^^
I would feed raw if I had the chance, money, and space. I am not convinced that one diet could work for all dogs. That's already been disproved with people, why can't you believe it is so with canines?
Of course not just one diet could work for all dogs, but the core idea that makes up a PMR diet is that of meat, bone and organ which will work for any dog out there if done
correctly. I believe that individuals differ in what animals sources work best with them. Some dogs do better on chicken while others do better on beef. That is the extent to customizing a PMR diet to an individuals needs.
I think that you cannot compare a human's diet to a dogs diet, and with that the different diseases in humans that relate to with food (although I am a strong believer in the "raw diet" for humans as well...and I think that most of human diseases would disappear if people ceased to eat processed and inappropriate diets).
For one thing, humans are omnivores. Our diet can consist of a huge variety of things because of this fact. But because dogs are carnivores, they thrive best on meat, bone and organ from a variety of different animals. You can just look at simple anatomy to discern this yourself. This is not my opinion, but fact that you can find anywhere:
What does your dog's teeth look like? Sharp and pointy...for ripping and tearing through meat and bone. Our teeth are mostly flat, for grinding and chewing food well.
Jaw musculature, movement and strength? Very strong and muscular, and can only move up and down. This signifies that their teeth or jaws are not designed to "chew" or mush their food up like we do. The way that our jaws are hinged, makes it possible for us to move our lower jaw back and forth...go ahead...try it. Dogs cannot do this.
Digestive tract? Very limited and much shorter than ours. Digestion of meat an bone only takes about 6-12 hours from one end to the other. Kibble on the other hand takes up to 24 hours from end to end, which tells me that dogs are really not designed at all to handle a diet based on grains or plants.
Digestion? For dogs, digestion does not start in the mouth like it does for us. They crunch their food enough so it will fit down the hatch and that is it, which is why they don't "chew" their food like we do. Simple digestion starts off in the mouth with us humans...which is one reason why we can be considered omnivores.
With just these four reasons, considering dogs as carnivores is enough for me. But I will break it down a bit more...
If you were to add veggies and fruit to a dog's diet, you would have to first puree them, so as they at least get some nutrition from them. Why is this so? Because dogs lack the digestive enzymes and symbiotic relationships with bacteria, fungus and microorganisms to be able to break down cellulose...ie the building block of plant cell walls. To be able to get any nutrition out of fruits and veggies, you have to break that cell wall. This applies to us as well (think about the last time you ate corn???).
The only animals that are capable of breaking down plant cell walls are ruminants and some rodents. Which is exactly why you feed meats bone and organs from
these animals to our carnivores. In essence carnivores are relying on their prey items to break down plants (fruit and veggies), get to the nutrients inside, and provide it to them for their well being. So, in reality there are no nutrients that are missing for a carnivore in meats, bone and organs.
